random ticking and misfire

Discount BMW Parts

These guys have Bosch 12-13-8-647-689 for 31.10 each. But.... it is only for build dates from 10/2002 forward. I see you have an 03, but you will need to check the steel sticker in your door to confirm when it was built to see can use these. You will be just under 190.00 shipped to your door if your build date is not to early.

Depending on if you need the spark plug connector or not you can get them as low as 40.38 each if you have an earlier build date. I wouldn't pay autozone prices unless you might need to take them back or something.

Thank you for the information the misfire has been fixed but the rattling noise is still slightly there but much quieter and less frequent. I'm thinking that noise is either a exhaust rattle or possibly the clutch fan. I still haven't pinpointed the location of the noise and since it is random and now i have no check engine light It makes it hard to find.

Sometimes it sounds like its coming from the top front. Sometimes it sounds like the top middle. Sometimes the top back of the motor sometimes the bottom of the motor sometimes it sounds kinda like that transmission. But if has never sounded like it was coming from the drivers side. maybe the clutch fan, Maybe the valves, maybe the exhaust i don't know but i would prefer to wait till it's a bit warmer outside to be crawling all over the ground and tearing it all apart.

trashed it.

Well it looked like sand and felt like sand and since that pos former roommate told me i had to get rid of it and get a truck i was looking at a used 335d and he told me i had to get a truck or he would trash the car. Also given that he had a small pile of sand in the back yard and the only person that could have gotten the keys since the last oil change.
I am planning to get something else i was looking at maybe a 2015 Subaru WRX STI or a 2015 Mitsubishi EVO. Iwant something AWD and something with enough power and options thats not going to cost to much for payments and insurance. Also must be a new vehicle car or suv.

Basically im just trying to keep this x5 running till i get something new if i can get it to last till next spring i can easily afford a nice down payment and keep payments low.

Quite frankly, I would be paying your former room mate a visit, with copies of all invoices/receipts/repair bills and demanding to know what else he/she has done to the vehicle. A bit of 'muscle' at your side, may influence the situation and could result in a positive outcome. I can't believe anyone would do this to someone else's vehicle intentionally. You must have really pissed him / her off!

well first if I got back there it will be to kill him. as to why he did that to my vehicle well I have a few ideas. He was trying to manipulate me into doing what he wanted. little things at first and over a couple months times of him ragging on me to get rid of my bmw and get a truck because "he could do so much stuff but couldn't afford to buy one himself" I moved in to help him pay for the house since he lost his job.
There really is to much to list but if I see him again I WILL kill him. and it has a lot to do with me being at work and coming home to find he had gone through my stuff and thrown a bunch of it away. when confronted about it threats and harassment began and I had to leave before he did something worse then he had already done.
I had to get identity protection because he stole my tax info, medical info, and social security card as well as emptied my bank account.

but enough about that back to the bmw.. I have a good update yippy I think.

OK UPDATE! a good one I hope...

well after 8 oil changes, 3 motor flushes and a couple hickups I think "think" I know what the problem is.... crossing fingers

the noise which again is completely random sounds strongest from one of the cats on the exhaust. It sounds like the internals of the cat broke loose and are rattling around in there. before the rattling noise started I would get about 450 to 475 miles to a tank of gasoline. since I have done all the oil changes and a few other little things I seem to be getting between 500 and 550 miles to a tank.
Please understand if this motor blows I will be getting either a brand new car or one with less then 40k miles on it. I have not been gentle with it lately. The rougher I am the better it seems to run no more misfires and as long as I'm above 1400 rpm it does not rattle.

I will be ordering an endoscope soon so I can look up into the cats so I don't have to take much apart until I figure out if that's the problem.


Also other good news I have a job doing what I enjoy doing and have turned down 3 other jobs one for low pay, one because of distance, and the other just because I don't like that type of work. Finally I back to building a bank account, money going out is less then 1/4 of what is coming in. Soon I will be able to pay someone else to fix my car for me. that will be one less worry. I may buy a chevy silverado only bad on it is the body rust for a winter/ beater vehicle to use while I work on the bmw.

OMG just came up to your thread and hhaha iave had a similar rattle for like 5 yrs now and my mechanic and couple of shops had confirmed it as a broken cat but since i didnt throw codes and it ran fine not issues i decided to live with it. but ill record my rattle and your right....if i rve to 1500 and let go i hear the rattle like a can lol but under normal driving not a sound only when i get off the gas....

i was told the exhaust pressure keeps the broken or loose cat in one place and the minute i let of the decrease in pressure allows it to rattle ....
